1 Enoch 91:4
3 And he spake unto all the children of righteousness and said: 'Hear, ye sons of Enoch, all the words of your father, And hearken aright to the voice of my mouth; For I exhort you and say unto you, beloved: Love uprightness and walk therein. 4 And draw not nigh to uprightness with a double heart, And associate not with those of a double heart, But walk in righteousness, my sons. And it shall guide you on good paths, And righteousness shall be your companion. 5 For I know that violence must increase on the earth, And a great chastisement be executed on the earth, And all unrighteousness come to an end: Yea, it shall be cut off from its roots, And its whole structure be destroyed.
Didache 2:4
2 You shall not murder; you shall not commit adultery; you shall not engage in sodomy; you shall not commit fornication; you shall not steal; you shall not practice magic; you shall not use love potions; you shall not cause abortion, nor kill newborns; you shall not desire your neighbor's possessions. 3 You shall not commit perjury; you shall not lie; you shall not speak ill; you shall not bear grudges. 4 You shall not be double-minded or speak with a double-tongue, for to do so leads to death. 5 Your words shall not be false or meaningless but followed by actions.
Notes and References
"... While the second instance, which brands “those of double heart” as a group, does not allow for ambiguity that conceives of them doing good as well as bad, the first occurrence holds open the possibility that anyone, perhaps even the righteous, might be subject to the “double heart”, and so warns them away. This point cannot, in the end, be pressed too far. The remaining emphasis on “two ways” throughout chapters 91–105 distinguishes the righteous and sinners or oppressors as social groups to such a degree that it is more likely that the righteous are simply being warned away from getting into a state of dividedness (i.e. sinfulness) to begin with ... A similar use of the motif of “double-mindedness” occurs within the “two ways” instruction in Didache 1:1–6:3; see especially 2:4 and 4:4 ..."
